Dr. Sue Sisley, renowned medical cannabis researcher and expert, will lead an information session on medical cannabis and its potential for treating a variety of ailments and diseases. This discussion will take place on Thursday, April 7, at the Pahrump Senior Center.

“Information will be presented to seniors and veterans who want to learn about the benefits of medical marijuana, especially if they have a condition that could make them eligible," Dr. Sue Sisley said. "We will also provide resources for obtaining your medical marijuana card.”

Dr. Sisley is the medical director for The Grove. She is also a member of the Nevada state medical marijuana commission (ILAC). Her 20-year work with veterans has been noted as groundbreaking. She is the SITE principal investigator for the only FDA-approved research using whole plant medical cannabis, which studies the risk and benefits of cannabis for combat veterans with treatment resistant post-traumatic stress disorder (PTSD).

Karma Holistic Health Foundation will be on site to walk applicants through the process of getting a medical marijuana card. This session is free and open to the public.

MIAMI, FL - A South Florida man is setting out to promote the use of medical marijuana.

Billboards are popping up along Sample Road in Broward County that are targeting senior citizens.

The more ornate billboard says, 'Legalize Medical Marijuana. I'm a patient not a criminal' and another depicts an elderly person in a wheelchair.

Down the road, another billboard reads 'Reschedule Medical Marijuana, one of the safest therapeutically active substances known to man." CBS4's Cynthia Demos spoke with folks who drove by the billboard.

"For my family I don't like it," said Roseanne Alves.

"Marijuana is a gateway drug," said Zed Castro.

The billboards are the work of 69-year-old Robert Platshorn.

Platshorm said he spent 30 years in prison for smuggling marijuana, a substance he says can help people and shouldn't be illegal. He doesn't want others sent to prison for what he calls, 'not committing a crime', so he is trying to make it legal.

"The billboard is a way to bring attention to the cause," Platshorn said. In the four years he's been out of prison he started his cause, "The Silver Tour" to promote the legalization of marijuana for seniors.
